In December 2016 Facebook deleted the 1001 Fesses page, which at the time had around 6,500 followers, because it deemed it had "pornographic content."

Since then they set up a new Facebook page, and they're in the process of rebuilding their butt loving community "one open-minded follower at a time."

So far the pair have photographed hundreds of women in Quebec, France, Belgium and Switzerland. But through a crowdfunding page, they are hoping it make it around the world. Bring on Australia!
